I am actually unable even to figure out how to get to a screen that would show me an error code, it only currently says "system malfunction".

Hi,

 

I will have to hand this off to another expert as I have to get going here, someone should be along very soon.

 

Thanks

Press and hold the right side button for 3 seconds. This will display the current active system faults

It doesn't give me a code, but it says "outside sensor error"

Expert:  Kenton Guidry replied 7 years ago.
There you go. Your outdoor sensor is giving you the trouble code.

Is there anything I can do now so that I can get my ac working again? It is REALLY hot here!!!
Expert:  Kenton Guidry replied 7 years ago.
The following is from your manual.

The user can press the right side button to dismiss the notice. The
regular run mode screen will then appear except “SYSTEM
MALFUNCTION” will appear in place of the day/time. If the error
has not disappeared within 24 hours, the above display will return.
If the error code disappears, “SYSTEM MALFUNCTION” will
disappear and the day/time will reappear.
